UNITED STATES PATENT OFFICE.

WILLIAM ROBINSON, OF BELLEFONTAINE, OHIO.

IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. I7 1,172, datedDecember 14, 1875; application filed October 4, 1875.

To all whom it 'may concern:

Be it known that I, WM. ROBINSON, of Bellefontaine, in the county ofLogan and in the State of Ohio, have invented certain new and usefulImprovements in Oar-Oouplings; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, lnaking a part of this specification.

The nature of my invention consists in the i construction andarrangement of a carcoup ling, as will be hereinafter` more fully setforth. In Aorder to enable others skilled in the art to which myinvention appertains to make and use the same, I will now proceed to(leto couple either high or low, as required.

Above and below this partition is a chamber, b, for the-coupling-link,the two chambers being connected by a passage, b', through which thecoupling-pin is to go. In the back part of the draw-head B is formed arecess or chamber, d, in which the tongue `D is placed. This tongue isof the peculiar formation as shown in Fig. 1, having at its lower end ateat or projection, c, fitting in a curved notch, fr, in the bottom ofthe chamber d. In the tongue D is a curved slot,, through which passes apin, h. The tongue D does not rest on this pin, but the pin simply holdsthe tongue in its proper place. The front edge or side of the tongue Dis cut out, as shown, to form, as it were, two projections, p p', one ofwhich rests upon the inner end of the coupling-link when the same is inthe draw-head, whether it be in the upper or lower portion thereof, thusholding the link in proper position to enter the opposite draw-.head incoupling the cars. In the top of the draw-head is an aperture, m, forthe passage of the coupling-pin O, which has a short pin, k, passedthrough it, and projecting a short distance beyond both sides of thecoupling-pin. In the lower front part of the aperture m is a shoulder,n, on which the coupling-pin O may rest when the cars are uncoupled, andit is not desired to couple them together. In the lower part of theaperture m is a short groove or recess, y, for the pin k to pass intowhen the coupling-pin is to be placed on the shoulder a.

When the coupling-pin G is raised, the tongue D falls forward in theposition shown in Fig. 1, so that, for coupling, the couplingpin O maybe supported on the upper end of the tongue, which is convex, as shown,so that when the link E enters the draw-head, either above or below thepartition a, and strikes the tongue, it will readily pass from under thecoupling-pin, and allow the same to fall down for coupling the cars.

Having thus fully described my invention, what I claim as new, anddesire vto secure by Letters Patent, is-

The tongue D, constructed as described, with front projections p p',curved slot i, and teat c, in combination with the two-mouthed draw-headB, provided with the chambers, as described, and with the recess and thetongue loosely connected therein by the pin h, all as and for thepurposes herein set forth.

In testimony that I claim the foregoing I have hereunto set myhand this13th day of September, 1875.
